PRONUNCIATION STRUCTURE, ROOM-CONSTRUCTING PANEL HAVING PRONUNCIATION STRUCTURE, ROOM, AND CABINET

摘要

PROBLEM TO BE SOLVED: To generate a loud sound by a simple pronunciation structure using an actuator for a vibration output. SOLUTION: The pronunciation structure is provided with a pronunciation tool 12 having a vibration plate 12a spreading in a face shape, a vibration propagating tool 13 connected to the pronunciation tool 12 extended along a face of the vibration plate 12a, and the actuator for the vibration output to transfer an output vibration to the vibration propagating tool 13. The face shape of the vibration plate 12a includes a flat face and a curved surface. The pronunciation tool 12, the vibration propagating tool 13, and the actuator 14 make a simple structure to pronounce thereby, and the loud sound is generated by transferring the vibration output by the actuator from the vibration propagating tool 13 to the pronunciation tool 12 efficiently.
